Nope they sure arent...

Series II is 48-55 Psi... Falling a few psi short at dead idle( Vacume applied to the FP reg ) is normal... You could see several Psi lower than the low rating...

A little on the lower side... But within range, I'd say for the time being you are ok... What pressure do you have with the Vacume applied and the engine idling?

cvc, with those readings there should be nothing wrong with your pump or regulator for running conditions. If you are having a hard start condition, then we will need to know what the fuel pressure drops to after the pump cycles off. This is refered to as a bleed-down test.

What is your reason for checking the pressure? Whats your complaint?
